Bypass Oil Filtration

[Cummins2014]

I dont think there is any benefit from a bypass oil filter in our application.
Especially not with todays main oil filter quality like Stratapore from Fleetguard.

Suspending "things" in oil is better than not doing it, as it keeps in circulation to filter or dump at oil changes. At least that is what I was taught as a kid in the Texaco family business and Havoline oil. What has changed? Oil filters are much better now also. SnoKing

What you didn't drink the Koolaid, good for you. My dad was a lab technician for an oil refinery. I learned a little about lubrication from him ,naturally he was old school , oil got change a lot more frequently . I have followed him on a lot of maintenance items on vehicles.

At the same time there are better full flow filters (thou Stratapore hasn't stepped up it's game like Fleetguard has with its fuel filters) which have reduced the need for bypass filters. If I ran a Stratopre filter I would be installing a bypass, but IMO the specs of the Donaldson ELF7349 don't require one.

Yes I know plenty of people get plenty of miles with Stratopre, or even POS OEM filters... but knowing the spec's I can't in good faith run them

With my 2 micron bypass installed, i feel comfortable running the OEM mopar or wix. I do have a few Strats and Amsoil (Donaldson) in the shed. But when those are gone, i may be buying $7 OEM or what ever is cheap. As long as the filter media doesn't collapse and completely block oil flow, it will filter well enough. The bypass filters the whole sump every 20 mins at highway speed anyway.

I've asked in a separate thread about this but is seems relevant to oil particulate/soot.

Centrifugal oil filter? I'd never heard of them until a few days ago. Any thoughts or experience?

Same answer as before, no need for it, no benefit from it.
If you really WANT to improve, what isn't needed, go with the LF9028 and be happy.

Here is an option i wasn't aware of when i installed mine. It costs as much as 2 filters.

But most like to leaventhe bypass on longer than 6 months.

I installed that filter a week ago, perfect solution for me as I frequently go above the factory intervals.

Thanks for mentioning that good Filter.

PS: I ordered directly from Cummins and picked it up at the Bloomington Location, next stop was a Valvoline exchange station to finish the job, Cummins didn't want to do the oil job on my truck.

I didn't know it was good for more than 15k miles

On my old I should change every 6K and that's not a lot if traveling.
I change at places that are convenient.

I guess i posted that link so long ago, i forgot that it said "extended service".

But i wonder if it ia Cummins/fleetguard that recommends it for extended service..... Or just the retailer that says it is OK for extended service.

The advantage of the byoass is you can run the bypass for 60k while changing the OEM filter (or which ever brand you use) at less than 15k.

I tried extended oil changes using an amsoil bypass setup on my 04. The first sample I sent in was at 15,000 miles compared to my usual 7,500 mile change. I got a report back telling me to change the oil immediately due to soot thickening. My 7,500 mile reports were always good. So much for bypass filtration removing soot.
P.s. The def equipped trucks don’t put anywhere near as much egr in the motor as you think.

I had a similar experience. No benefit to the bypass setup that I have noticed based on oil analysis. The only reason I keep it on the truck is that it makes taking samples really easy.

According to oil samples you will likely also see no benefit to using stratopore filters vs. OEM filters. Both the mopar and stratopore will give UOA samples reaults with less than .5% particles.

But many still go with the stratopore......

Some literature from Parker/Racor.

I don't know if their conclusion about longer equipment life is accurate. But their claim of less wear sits comfortably with me

It is Cummins that says that, with our Engine but in different applications, one is Carrier one is Kubota.
Anyway I use it and I'm happy with it.

Some of you seem to be quibbling over language issues. If you're running an LF9028, you're ALSO running a bypass filter. If you like what the LF9028 does for you, you will also like what an external bypass filter does. Other than capacity, they're the same.
